Which Pyrex Lid Fits Which Bowl? The Complete Replacement Lid Size Guide

This guide covers the most common Pyrex and CorningWare lid models, their dimensions, the dishes they fit, and how to read the alphanumeric codes stamped on the bottom of your cookware. Whether you need a replacement lid for a round mixing bowl, a square CorningWare casserole, or a Visions cranberry saucepan, this is your reference.

Understanding Pyrex Lid Model Numbers

Every piece of vintage Pyrex and CorningWare has a model number stamped or embossed on its base. The lid that fits it carries a matching number with a -C suffix (for "cover"). So a CorningWare casserole dish marked A-5-B takes a lid marked A-12-C — the -C tells you it's the cover.

The letter prefix identifies the shape family: A is square, F and DC are oval, G and P are round. The number indicates size within that family. Once you understand this system, shopping for a replacement Pyrex lid becomes much simpler.

CorningWare Square Casserole Lids

Square CorningWare casseroles are the most commonly searched category for replacement lids. They were produced across several decades and the dish-to-lid pairing is very consistent.

One important note: the A-12-C lid fits two different dish sizes (the A-5-B and the larger A-10-B) because CorningWare used the same lid footprint for both. If your square CorningWare casserole is unmarked or the stamp is worn, measuring the rim diameter is the most reliable approach (see the measuring section below).

CorningWare Oval Casserole Lids

Oval CorningWare dishes — often used for smaller casseroles and roasts — take a different lid family. The most common oval replacement lids are in the F and DC series.

Round CorningWare & Visions Lids

Round lids are used across both the CorningWare G-series casseroles and the Visions amber and cranberry cookware. These are among the most searched replacement Pyrex lids because Visions saucepans were heavily used and the lids are prone to chipping.

How to Measure Your Dish for a Replacement Lid

If the model number is worn off your dish, measuring the rim is your best fallback.

1. Measure the inside rim diameter — not the outside of the dish. Place a ruler across the top of the opening and measure from inside edge to inside edge.
2. Note the rim profile — is it flat, slightly recessed, or does it have a seating groove? Some Pyrex dishes have a ledge the lid rests on; others rely purely on diameter fit.
3. Check the shape — square, oval, or round. Measure both the long and short axes to confirm oval dishes.
4. Note the dish depth — helps confirm the series (casserole vs. skillet vs. saucepan) when cross-referencing.
5. Contact us with your measurements — if you're still unsure, reach out through our contact page. We've identified hundreds of vintage pieces and can usually match your lid from dimensions alone.

Amber vs. Clear vs. Cranberry: Does Color Affect Fit?

Color indicates the glass formula and production era, not necessarily a different fit — but there are important exceptions. Clear glass lids were used across the widest range of CorningWare dishes. Amber lids were used primarily with early Visions cookware in the 1980s. Cranberry lids are specific to the Visions cranberry series and are generally not cross-compatible with amber Visions pieces, even where diameters are close.

For pure functionality, a clear lid in the correct model number will seal and perform identically to the original amber or cranberry equivalent in most cases — but always verify by model number first.

What About "Dinged and Chipped" Lids?

Our Dinged and Chipped collection offers fully functional lids with minor cosmetic imperfections — small rim chips, light surface scratches, or minor knob dings. Every lid is personally inspected and confirmed safe for use; we don't sell anything with structural cracks.
